  Prevent process form shutting down when calling WebFrameProxy::prepareForProvisionalNavigationInProcess

Reviewed by Pascoe.

Similar to code in WebPageProxy::triggerBrowsingContextGroupSwitchForNavigation
and WebPageProxy::continueNavigationInNewProcess, if we do anything asynchronous between
the point where we decide to use a process and the point where we actually start using it,
we need to make a shutdown preventing scope.  Otherwise, we hit the release assertion
in WebPageProxy::continueNavigationInNewProcess, which happened occasionally when loading
to and from complicated web pages with site isolation enabled.
